lVIACI-IINE FOR. CLEANING GRAIN.

Specfication of Letters 'Patent No. 1,608, dated May 19', 1840.

T all whom it may concern Be it known that I, SAMUEL SPANGLER, of thetownship of Stoney Greek, in the county of Somerset and State ofPennsylvania, have invented a new and useful Machine to Clean Grain bySeparating the Smut Therefrom, called Spangleris Improved Smut-Machine,and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the annexed drawings of thesame, making part of this specification.

The nature of my invention consists in a certain new and usefularrangement of revolving fans in a perforated case for separating thesmut from the grain and cleaning the same.

To enable others skilled in the art to which this appertains to make anduse my invention I will proced to describe its construction andoperation.

Figure l is a view of the outside of the case containing the revolvingfans and the bands and pulleys by which they are revolved-the frame tosupport said case and the axles of the fans, being omitted. Fig. 2 is avertical section through the case and fans; Fig. 8, front view; Fig. 4,top view.

The frame containing and supporting the case and fans may be made yofany convenient form, size, and Strength. One of the followingdescription will answer very well. It may consist of four sides, eachside being separately framed. The two trusses on opposite sides may beframed eighteen inches from out to out, the posts four feet three incheslong in the clear between the shoulders and l-; by 2 inches square. Eachpost is to have three cross-bars for the axles of the pulleys to run on.The first bar is 9 inches from the top of the post to the top of thebar. The second bar may be two feet one inch from the top of the post tothe top of the bar and the third bar 9 inches from the lower end to thetop of the bar. These bars are to be 1-15 by 2 inches square of goodsolid wood; the other sides the same length and framed ten inches wiclein the clear and have a bar at the top and one seven inches from thebottom to the top of the bar and between these two other bars at equaldistances.

The case C containing the revolving fans may be made in the followingmanner. The two broad sides may be made of sheet iron punched. Thenarrow sides must likewise be of perforated sheet iron punched from vthe outside as full of holes as the iron will fans or beaters F Fconsisting of two orl more aXles or shafts B 1% inches square seventeenand a half long to project out of the box four inches to receive pulleysP to be turned by straps S three inches wide passed around them. Onthese shafts inside the case there must be four or more fans F four oneach shaft as the grain may require. These fans, or beaters, must bemadeof heavy sheet iron and be sixteen inches from out to out and S-- incheslong, and they should have from six to nine hundred revolutions in aminute as the grain may require. The top of this box must be shut with asheet iron cover D having a hole H in the center, of one and a half bythree inches to let the grain pass into the machine through a ho-pperplaced over said opening. There must be a common fan I at the lower endof the box where the Wheat comes out to blow out the bran which ispolished off the Wheat.

Operation: The o'rain to be cleaned is put into the hopper-firom whenceit descends into the box, Where it is struck by the revolving fans whichthrow the grain with great violence against the roughened sides of thecase by which the smut is broken from the grain which being the lightestis driven through the perforations of the case into the atmosphere whilethe grain which is the heaviest descends and passes out of the lowerside of the case.

VVhat I claim as my inventio-n and desire to secure by Letters Patentconsists in- The before ldescribed fans arranged one over the other in aperforated case so that they shall act both as beaters and fans, asherein set forth, in combination with the fan I in the enlarged part ofthe case.

SAMUEL SPANGLER.
